The tissue surrounding craniofacial implants is prone to inflammation; however, no adequate instrument is currently available to measure this objectively.
The purpose of this study was to describe the parameters influencing the sulcus fluid flow rate in the extraoral periimplant tissue environment.
Thirty-four patients with 112 craniofacial implants participated. The sulcus fluid flow rate (SFFR) was measured with standardized paper strips. The influence of cleansing liquids, implant location, presence of purulent exudates, smoking habits, depth of crevice, and previous irradiation on the sulcus fluid flow rate were evaluated with covariate adjusted finite mixture models.
Two latent subgroups of SFFR were identified based on a mixed model. The majority (95.5%) had a mean value of 1.44 mm, and the smaller subgroup (4.5%) had a mean value of 10.4 mm. The SFFR values were increased when purulent exudates were present (regression coefficient 1.41), 95% CI (0.67, 2.16). The depth of the crevice influenced the SFFR per unit depth (regression coefficient 0.37), 95% CI (0.22, 0.53). Additional covariates, such as the implant location, history of smoking, and prior irradiation, had no statistical effect on SFFR.
SFFR can be measured objectively in the extraoral periimplant tissue.
颅面植入物周围的组织容易发生炎症；然而，目前没有足够的仪器可以客观地测量这种炎症。
本研究旨在描述影响口腔外种植体周围组织环境中龈沟液流速的参数。
34 名患者的 112 个颅面植入物参与了本研究。龈沟液流速（SFFR）使用标准化的纸条进行测量。评估了清洁液、植入物位置、脓性渗出物的存在、吸烟习惯、龈沟深度和先前的辐射对龈沟液流速的影响，使用协变量调整的有限混合模型进行评估。
基于混合模型，确定了 SFFR 的两个潜在亚组。大多数（95.5%）的平均 SFFR 值为 1.44mm，较小的亚组（4.5%）的平均 SFFR 值为 10.4mm。当存在脓性渗出物时，SFFR 值增加（回归系数 1.41，95%置信区间为 0.67，2.16）。龈沟深度对单位深度的 SFFR 有影响（回归系数 0.37，95%置信区间为 0.22，0.53）。其他协变量，如植入物位置、吸烟史和先前的辐射，对 SFFR 没有统计学影响。
可以在口腔外种植体周围组织中客观地测量 SFFR。
